Did you put gears in your truck to get the 4.10 ratio? Was it a big deal to do and about how much? I have a 2006 Colorado only 20000miiles and have 18's on it with BFG tires. All i have done is tighten the torsion bars a little and put a longer shackle in the back to raise the rear of the vehile to the front. I have terrible luck on gas mileage. I get the best is 16.5 and i have but in a K&N Charger Kit and a Throttle body spacer and Magnaflow duals with high flow cats. I dont know what else to do to get good gas mileage?

I have the 2005 I5 3.5ltr 4x4 regular cab. I have the factory tanau (not sure if that's spelled correct) cover but I doubt it does much.

Anyway, I usually drive 90% highway with it and have gotten an average 26mpg over 50,000 miles. That's using synthetic oil every single time and only using 93 octane gas. I don't have a lead foot either. The whole truck is still factory spec. No special intakes or mufflers.

I agree with the other gentleman here... I'm not a fan of the tires either. I think I'll put Toyo's on there when they need changing.
